Electricity: 299,867 kWh pa

Project Overview

Property managers Knight Frank worked closely with enLighten Australia to scope the LED lighting upgrade for the fire stairs in both the commercial office
tower and wing and 300 space underground 2 level car park.

The property owners are committed to owning an environmentally sustainable portfolio and operating the portfolio in a way which minimises resource use and mitigates the potential effects of climate change.

Fire stair meter data supplied by Knight Frank indicated an average 85% reduction in lighting electricity usage. Monthly
electricity usage across the two tower fire stairs dropped from a pre installation average of over 8,400kWh to a post installation average of 1,250kWh.

Project scope

ISPT is one of Australia’s largest unlisted property funds with over $7 billion of funds under management. ISPT is committed to owning an environmentally
sustainable portfolio and operating the portfolio in a way which minimises resource use and mitigates the potential effects of climate change.

Sustainability initiatives implemented across the commercial property portfolio since 2006 have resulted in $10.5million savings to ISPT Core Fund investors
through electricity, gas and water savings. The average weighted NABERS rating for the portfolios base building is over 4 stars, with a target average
rating increase to 4.5 stars by June 2012.

Upgrade of lighting systems in properties has been amongst ISPT’s sustainability policies. In response to this policy, at 477 Pitt St, property managers
Knight Frank worked closely with enLighten Australia to scope the LED lighting upgrade for the fire stairs in both the commercial office tower and
wing and 300 space underground 2 level car park.

Electricity savings results

Fire stair meter data supplied by Knight Frank indicated an average 85% reduction in lighting electricity usage. Monthly
electricity usage across the two tower fire stairs dropped from a pre installation average of over 8,400 kwH to a post installation average of 1,250kwH.

Indicative car park meter data provided by the metering system also revealed a significant reduction in energy usage.

Project ROI

Calculation of the LED retrofit project ROI of 1.5 years is inclusive of electricity, maintenance savings and Energy Savings Certificates.

The property owners applied for Energy Savings Certificates (ESCs) generated from the commercial lighting upgrade project under the NSW Energy Savings
Scheme. The project’s Accredited Certificate Provider has indicated that 1430 certificates will be generated from the project.
